The main components of an afterburning turbofan include the fan, compressor, combustion chamber, turbine, exhaust nozzle, and afterburner. Each part plays a specific role in capturing air, compressing it, mixing it with fuel for combustion, extracting energy from gases to power other components, directing gases for maximum thrust, and finally increasing thrust through additional fuel combustion.
Some advanced fighter jets can now reach supersonic speeds without using their afterburners due to improvements in engine design. Notable examples include the F-22 Raptor equipped with Pratt & Whitney F119-PW-100 engines capable of super-cruising thanks to their thrust-vectoring capabilities.
"Flying with the afterburner engaged for prolonged periods increases fuel consumption and heat stress on the engine," highlighting why supercruise capability is significant.
Afterburners can increase a jet engine's thrust by 50 percent or more without significantly adding weight or complexity. However, not all takeoffs require their use; they are typically engaged when launching from short runways or aircraft carriers.
Naval aviation models like the F/A-18E/F Super Hornet incorporate afterburner technology as part of their design to assist in carrier launches. Even non-military aircraft such as Concorde used afterburners during takeoff when needed.
The F-35 Lightning II uses a Pratt & Whitney F135 engine featuring an integrated afterburner but emphasizes stealth over sustained high-speed performance. While details about its full capabilities remain classified due to its newness as military hardware developed by Lockheed Martin’s team members involved directly within this project space environment
